These days, almost all business communications happen over email. If the mail server goes down for any reason, all mails in that server will bounce, causing significant business disruption.

For shared hosting providers, this is a major issue, as a single server hosts hundreds of businesses, and a service failure can affect all of them. During such a downtime, hosting providers are usually flooded with support requests to recover lost emails.(more…)

Backup MX – A great way to quickly recover from mail failures was last modified: July 14th, 2018 by Reeshma Mathews

I encountered this issue one Saturday afternoon, on which I happened to be working. Being a Saturday, I expected a relatively quiet day at the office. This was why, I was initially surprised when our monitoring software reported that there were more than 3500 mails present in one of our servers (say, vm.domain.com) mail queue. Within half an hour, the count had increased to approximately 5000 mails. There goes my quiet Saturday. Sigh.

Before proceeding, I would like to point out that all our servers run on CentOS and use Postfix.

I have been dealing with quite a large number of clients, their queries and feedbacks for the past few months. The common thing that I noticed with all is the hurry to fix the issue concerned about the downtime for their business. We all undoubtedly hope for a tension free life, and why should a troublesome and complicated mail issue in your hosting drive you nuts???????

It is in this sense that the option Exim + cPanel becomes relevant. In most of the Exim issues that I handle, what I see in the end is loads of thanks replies admiring the advanced and unique features of Exim. I hope that I will be able to explain quite a few of the reasons for those happy endings!!!!!

A mailing list is actually a list of mail addresses, to which the same information/content is sent. Suppose you have to send an announcement to all users of a particular service, say customers who use your enterprise backup solution, all you need to do is to send it to a mailing list comprising of all such user’s mail ID’s.

Adding a mailing list in cPanel is a fairly easy task. Let us see how this can be done easily, from within the cPanel account :

No, I’m not talking about spam. Depending on the type of customers you host on your servers, they may have to send out bulk mails to their customers. If they’re not careful, they could get you’re server’s IP address blacklisted! This would be an inconvenience for you, and for the other customers you are hosting on the same server. Lets take a look at a few steps that can help you avoid that.
